Hanshinkan Modernism (阪神間モダニズム) identifies the modernist arts, culture, and lifestyle that developed from the region of Japan centered primarily on the Hanshinkan conurbation between Osaka and Kobe, the ideally terrained area between the Rokkō Range and the sea (Kobe's Nada and Higashi Nada wards, Ashiya, Takarazuka, Nishinomiya, Itami, Amagasaki, Sanda, and Kawanishi) from the 1900s through the 1930s, or the circumstances of that period.
Accompanying the suburbanization of the Osaka Bay area, which continued to grow after 1923 in contrast to the Tokyo Bay area where the spread of urbanization was temporarily suspended due to the Great Kantō earthquake, the Hanshinkan Modernism cultural sphere spread to Ikeda, Minoh, and Toyonaka in Osaka Prefecture, and to Kobe's Suma and Tarumi wards.
